Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40828, here are decompositions:

5 + 40823 = 40828
41 + 40787 = 40828
89 + 40739 = 40828
131 + 40697 = 40828
191 + 40637 = 40828
251 + 40577 = 40828
269 + 40559 = 40828
401 + 40427 = 40828

Showing the first eight; more decompositions exist.
